Requisition # 2026-22458
Posted 2026-10-28
Department: PPPL Discovery Plasma Science
Category: Research and Laboratory
Job Type: Temporary
Overview
The undergraduate research intern in HED and IFE project supports a research effort to develop a laser-driven alpha-particle source for investigating charged-particle transport and energy deposition in high-energy-density plasmas. The intern will work with a multidisciplinary research team to model the transport and energy selection of laser-driven alpha particles. Using Monte Carlo particle-transport simulations, the intern will investigate how particle energy, energy spread, divergence, source size, and selector geometry affect energy resolution and transmission efficiency. The student will contribute to the development and optimization of an advanced alpha-particle selector and help establish design requirements for future experiments. In addition, the student will have an opportunity to participate in a hands-on experiment at a world-class petawatt laser facility. This work is relevant to inertial fusion energy, plasma physics, particle-beam transport, and diagnostic development.
A U.S. Department of Energy National Laboratory managed by Princeton University, the Princeton Plasma Physics Laboratory (PPPL) is tackling the world's toughest science and technology challenges using plasma, the fourth state of matter. With more than 75 years of history, PPPL is a leader in the science and engineering behind the development of fusion energy, a potentially limitless energy source. PPPL is also using its expertise to advance research in the areas of microelectronics, quantum sensors and devices, and sustainability sciences. Whether it be through science, engineering, technology or professional services, every team member has an opportunity to contribute to our mission and vision. Come join us!
